From an economic point of view, HR is not wrong; But emotionally, this is indeed a disrespect for the interviewer. At least the interviewer is prepared, and it is really bad for HR to return directly regardless of face.

Matters needing attention in interview:

1. Don't be nervous, act natural and polite, and don't forget to greet the examiner and say "good morning".

2. Be generous, don't shrink back, be confident. Don't sit down politely before the examiner invites you. Don't be too casual or look around. Never pretend to be lazy or indifferent.

3. Smiling can relieve inner anxiety and make the interview atmosphere harmonious and pleasant.

Let the examiner know that you cherish this interview opportunity. When the examiner speaks, look at each other and listen carefully.
